Final answer:
Simplex channeling refers to the one-way transmission of data between a DTE and DCE. It is commonly used in scenarios where one-way communication is sufficient and more efficient.
Step-by-step explanation:
Simplex channeling refers to the one-way transmission of data between a Data Terminal Equipment (DTE) and a Data Circuit-terminating Equipment (DCE). In this case, the DTE either transmits data to or receives data from the DCE, but not both simultaneously.
For example, when you make a phone call, your voice is transmitted to the other person (DCE) through the network (DTE), but you cannot hear their response in real-time. Similarly, television broadcasts are transmitted from the broadcasting station (DTE) to your TV (DCE) in a one-way manner.
Simplex channeling is commonly used in scenarios where one-way communication is sufficient and more efficient.
